VHP and UHPLC fittings

The IDEX VHP (Very High Pressure) series is specifically developed for the extreme pressures found in modern HPLC and UHPLC systems. Where standard fittings reach their limit, the VHP line guarantees a leak-free connection for 1/16” or 1/32" tubing at pressures up to 30,000 psi (2,070 bar).
